Talk:Simple and accurate LOS function for BlitzMax

In the normal course of things, rays should never 'leak' through no matter what density you are sending out. Looking at your algorithm, I see that it is because you are increasing both x and y by a fixed amount every iteration. This means that if the line cuts through a square in the right way, then that square will never be checked for being blocked by a given line. The way to correct this is to do something closer to Bresenham's Algorithm. That would make the algorithm a bit more complicated, but would probably reduce artifacts.

Good point,
I should point out that with a step size of 0.18, I don't get any kind of visual artifacts and 100% uniform coverage in every map type.
